While performing security scans there were several
issue raised as G304 (CWE-22): Potential file inclusion via variable.
As some files path are taken from user input, it is possible the
filepath passed by user may have unintended effect if not properly formed.
This fix add Clean to remove the security warning and address some
potential issue.

Make normalize return multiple "hosts" (= reverse zones) when a
non-octet boundary cidr is given.
Added pkg/cidr package that holds the cidr calculation routines; felt
they didn't really fit dnsutil.
This change means the IPNet return parameter isn't needed, the hosts are
all correct. The tests that tests this is also removed: TestSplitHostPortReverse
The fallout was that zoneAddr _also_ doesn't need the IPNet member, that
in turn make it visible that zoneAddr in address.go duplicated a bunch
of stuff from register.go; removed/refactored that too.
Created a plugin.OriginsFromArgsOrServerBlock to help plugins do the
right things, by consuming ZONE arguments; this now expands reverse
zones correctly. This is mostly mechanical.
Remove the reverse test in plugin/kubernetes which is a copy-paste from
a core test (which has since been fixed).
Remove MustNormalize as it has no plugin users.
This change is not backwards compatible to plugins that have a ZONE
argument that they parse in the setup util.
All in-tree plugins have been updated.

* Speed up testing
* make notification run in the background, this recudes the test_readme
time from 18s to 0.10s
* reduce time for zone reload
* TestServeDNSConcurrent remove entirely. This took a whopping 58s for
... ? A few minutes staring didn't reveal wth it is actually testing.
Making values smaller revealed race conditions in the tests. Remove
entirely.
* Move many interval values to variables so we can reset them to short
values for the tests.
* test_large_axfr: make the zone smaller. The number used 64K has no
rational, make it 64/10 to speed up.
* TestProxyThreeWay: use client with shorter timeout
A few random tidbits in other tests.
Total time saved: 177s (almost 3m) - which makes it worthwhile again to
run the test locally:
this branch:
~~~
ok github.com/coredns/coredns/test 10.437s
cd plugin; time go t ./...
5,51s user 7,51s system 11,15s elapsed 744%CPU (
~~~
master:
~~~
ok github.com/coredns/coredns/test 35.252s
cd plugin; time go t ./...
157,64s user 15,39s system 50,05s elapsed 345%CPU ()
~~~
tests/ -25s
plugins/ -40s
This brings the total on 20s, and another 10s can be saved by fixing
dnstapio. Moving this to 5s would be even better, but 10s is also nice.

For the coredns/caddy repo the following changes have been made:
* anything not needed by us is deleted
* all `telemetry` stuff is deleted
* all its import paths are also changed to point to coredns/caddy
* the v1 branch has been moved to the master branch

Abstract the caddy call and make it simpler.
See #3261 for some part of the discussion.
Go from:
~~~ go
func init() {
caddy.RegisterPlugin("any", caddy.Plugin{
ServerType: "dns",
Action: setup,
})
}
~~~
To:
~~~ go
func init() { plugin.Register("any", setup) }
~~~
This requires some external documents in coredns.io to be updated as
well; the old way still works, so it's backwards compatible.

reload interval for the ticker.

* Default to upstream to self
This is a backwards incompatible change.
This is a massive (cleanup) PR where we default to resolving external
names by the coredns process itself, instead of directly forwarding them
to some upstream.
This ignores any arguments `upstream` may have had and makes it depend
on proxy/forward configuration in the Corefile. This allows resolved
upstream names to be cached and we have better healthchecking of the
upstreams. It also means there is only one way to resolve names, by
either using the proxy or forward plugin.
The proxy/forward lookup.go functions have been removed. This also
lessen the dependency on proxy, meaning deprecating proxy will become
easier. Some tests have been removed as well, or moved to the top-level
test directory as they now require a full coredns process instead of
just the plugin.
For the etcd plugin, the entire StubZone resolving is *dropped*! This
was a hacky (but working) solution to say the least. If someone cares
deeply it can be brought back (maybe)?
The pkg/upstream is now very small and almost does nothing. Also the
New() function was changed to return a pointer to upstream.Upstream. It
also returns only one parameter, so any stragglers using it will
encounter a compile error.
All documentation has been adapted. This affected the following plugins:
* etcd
* file
* auto
* secondary
* federation
* template
* route53
A followup PR will make any upstream directives with arguments an error,
right now they are ignored.
